LUCIEN A. MARSH, OF SAN FRANCISCO, CALIFORNIA.

, GAS-STOVE AND BURNER LIGHTING DEVICE.

Specification of Letters Patent.

Patented Oct. 3, 1916.

Application filed January 19, 1916. Serial No. 72,934.

To all whom it may concern:

Be it known that I, LUOIEN A. MARSH, a citizen of the United States, residing in the city and county of San Francisco and State of California, have invented new and useful Improvements in Gas-Stove and Burner Lighting Devices, of which the following is a specification.

y invention relates to improvements in devices for igniting gas at burners, such as are employed for gas stoves and'plates and the like.

It consists in the novel combination including two parallel supply manifolds forming a single element, connections between one of these manifolds and the burners proper and connections between the other manifold and a pilot light, and cooks having passages therethrough so that in turning a cock gas will be admitted first from one of the manifolds to the pilot light and upon a further turning of the cock gas will pass from the other manifold to the burner, at which point the gas from the burner will meet the jet of ignited gas which is directed from the pilot head to each of the burners, thereby igniting the gas at the burner at the instant of its escape to prevent any waste or disagreeable smell from unignited gas which might otherwise escape at the burners.

The invention also comprises detailsof construction which will be more fully eX- plained by reference to the accompanying drawings, in which Figure 1 is a plan viewof four burners with their intermediate pilot burner manifold and controlling cocks. Fig. 2 is a transverse section of the manifolds and a connecting cock and passages. Fig. 3 is a similar view at right angles to Fig. 2. Fig. 4: is a transverse section of the plug. Fig. 5 is a section taken on the line 5-5 of Fig. 1. Fig. 6 is a modification of the manifold.

Fig. 7 is a section of the pilot light. Fig. 8

is a modification of the same.

In my invention I have devised a simple arrangement by which the pilot light is independently supplied with a small constant jet of gas, and when any of the cooks to the main burners is opened, an additional supply of gas will be supplied, ignited and directed to the main burner head, so that at the instant when the gas is supplied to the main burner, it will be met by the flame of the pilot light and ignited without any escape of 'gas at that point.

As shown in the drawings, the gas supply is received through a main or manifold A, which extends horizontally and adjacent to the burners to be supplied. Pipes2 connect this main with burner heads 3, and these pipes have cocks 4 by which either of them may be opened to receive gas from the main In order to ignite any one or more of these burners a pilot light head is located substantially central between the main burners and approximately at the same level. This pilot light consists of a cylindrical case 5 having openings made through its side and directed to the main burners. 7

Within this case is the pilot burner-6, having jets 7 directed horizontally and through the openings 8 of the outer case; these jets, as above described, being directed to the mam burner heads. In order to supply this pilot light with a small, constant flame, the head is connected by a pipe 9 with the main A, and by means of a cook 10 an opening is made suificiently to allow a small constant supply of gas to pass through the pipe 9 to the pilot light in the casing 5. This flame is small and constant, but when any of the burners is to be ignited it is done by turning a. cock 4. This cock has a port which may be brought into line with the passage 11 leading through the pipe 2 to the burner. Below the contiguous jet main or manifold A, is a second main 12 which is closed at each end, but which has passages, as at 13, leading to the surface of the cock A. A diagonally disposed, channeled port 14 is formed in the surface of this cock and when turned to a certain position it will connect the passage 11, and through this cock and port and the passage 13 will supply gas to the closed main 12. The gas passing through this main will thus reach a port 15 which independently connects with the pilot light through a pipe.16 which is concentric with the constant supply pipe 9. These connections will be made as follows: Upon turning the cook 10 a smallijet will be supplied to the pilot head from the main A through the pipe 9. When the cock 4 is turned the diagonal surface port will be first brought into line with the passage 13 which connects with the closed main 12 and gas will im mediately pass into this main and will thence flow through the passage 16 and cock will cut off the igniting supply from the closed main 12 and willreduce the pilot light to its normal appearance, while the supply to the burner head may be increased or diminished by the further turning of the cock without any effect upon the reduced pilot light.

By the construction here described, it is possible to combine with the main gas conductor, a closed secondary chamber with a manually actuated means to transfer gas from the main through this chamber to the pilot light head so as to temporarily increase the flame at this point, and to follow this by a supply 'ofgas to the main burners, to be 'met and ignited by the pilot light flame, and to also re, ;ulatethe main burner flames independently of the pilot supply, with a minimum of pipes, cocks and connections.

Having thus described my invention, what I claim and desireto secure by Letters Patent is- 1. In a gas stove, a burner, a pilot light having a normally lighted jet and a second jet directed toward the burner, a two part gas manifold having a supply compartment and a return compartment, a pipe leading from the supply compartment of the manifold to the first jet of the pilot light to furnish a constant supplyo fgas'a second "pipe connecting the pilot light with the return compartment of the manifold to furnish a supply of gas to the-second jet, a connection between the burner and manifold supply compartment, and a cock arranged to open successively communication between "the manifold compartments and between the supply compartment and the burner.

2. The combination with a gas manifold, main gas burners, gassupply pipes connecting said burners to said manifold, and valves in said gas supply pipes, of an igniting device comprising a pilot light having a et designed to be constantly lighted and a plurality of igniting jets directed toa conduit connected with the pilot light tosupply the other jets with gas, a closed chamber connected with the burner pipes and with the conduit, and means whereby on operating each valve the gas will be directed into the closed chamber and successively with the respective burner.

8. In combination, a plurality of burners, a pilot light located between the main burners, a main supply manifold, direct conmotions and controlling cocks between said manifold and the burners, an independent connection and controlling valve to the pilot light, a chamber contiguous to the supply manifold, a connecting passage from said chamber to the pilot light, and passages from the chamber to each burner supply cook, the plugs of said cocks having ports by which gas may be transferred from the manifold to the chamber and to the pilot light.

i. The combination with fixed. burners, and an intermediate pilot light casing, of a contiguous gas supply manifold and a closed chamber, pipes and controlling cocks between the manifold and the burners, an independent pipe and cock between the manifold and the pilot light, a port from the closed chamber to the pilot light pipe, and ports from said chamber to the burner controlling cocks, the plugs of said coc' is having passages by which gas may be transferred from the manifold to the closed chamber and to the pilot light.

'5. The combination with a gas manifold, main gas burners, gas supply pipes connectingsaid burners to said manifold, and valves in said gas supply pipes, of an igniting device comprising a single chamber common to all the valves, the latter being provided with means for admitting gas from the manifold to the chamber prior to opening communication between the manifold and the respective burners, a pilot light adapted to direct its flame toward the burners, and a pipe connection between thepilot lightand the chamber.

{In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses.
